Me and my friend took part in the Game Maker's Toolkit Game Jam 2019 this weekend. The entire game was made in 48 hours.We made a nice little 3d puzzle platformer in FTEQW where you have to reach the goal in a golf-like game where you shoot your little slime blob around and collect diamonds and powerups.

I did all the code and most 3d models and textures, while my friend made most of the maps and all the sounds and music.

Yep, that's the source there, we used the git to sync our work while developing but also made the source public nicely. It should be MIT if I didn't remember to put a license file in, can't remember if I did.
